Title: Tyre, in particular for a motor vehicle
Inventor: EBERSPAECHER RALPH DIPL ING
IPC: B60C11/00
Filed: 1985-06-27
Abstract: In a motor-vehicle tyre whose tread is divided into at least three strips (1, 2, 3) by at least two circumferential grooves (26, 27), the central strip being constructed as a continuous strip, that is to say not provided with transverse grooves whilst the lateral strips are divided into cleat profiles (14) by transverse grooves (12), the running noise properties are substantially further improved if the angle (18, 19) of the transverse grooves (12) of the first left-hand lateral strip and right-hand lateral strip (2, 3) are selected to be comparatively small, i.e. an angle (18, 19) of 10 DEG  to 40 DEG  is provided. If further lateral strips (4 and 5) are present, the angle (22 or 25) of the second and third lateral strips (4 and 5) are selected in a region of 15 DEG  to 90 DEG , the angles (22 and 25) in each case being somewhat larger than the angles (18 and 19) but a small angle (25) being assigned to the small angle (19) and a large angle (25) being assigned to the large angle (19). In addition, the width (16) of the cleat profiles (14, 15) varies in the circumferential direction or in the running direction (17) measured from cleat profile to cleat profile. In this arrangement, the width of the cleat profiles varies from the smallest to the largest in the order of magnitude of approximately 1 : 3. Furthermore, the width of the transverse grooves (12, 13) from cleat profile to cleat profile is also selected to be different, it being possible for the absolute values to lie between two to twenty millimetres (passenger car) and five to twenty millimetres (lorry etc.). <IMAGE>

Title: Apparatus for casting lead grids for electric accumulator plates and a method for their manufacture
Inventor: KALLUP BERNHARD E DIPL ING DR
IPC: B22D25/04
Filed: 1985-08-20
Abstract: In a device for casting lead grids for electric accumulator plates, a highly porous ceramic mould lining is produced by flame spraying, preferably of zirconium oxide. A lining of this kind can consist of a thin surface coating on a profiled metallic basic mould or be a separately produced inserted plate (9) held by a metallic mould carrier. To produce it, use is first of all made of a die (5) with a surface contour (diverter lug 6, grid webs 7) corresponding to half the profile of the lead grid and acting as a positive mould onto which, after the application of an intermediate layer of an adhesion-promoting layer (8) which can be removed again, the ceramic (4) is applied by the flame-spraying method. The ceramic is then surface-ground and removed (9). When a thin surface coating is used, the application of masks to the metallic basic mould during flame spraying can be used to reduce the thickness of the ceramic layer in the region of accumulations of material in the grid, thus making the cooling of the casting more uniform. <IMAGE>

Title: Method of determining hypotheses or faults, taking into account uncertain features
Inventor: LIEBEL PETER
IPC: G06F17/18
Filed: 1987-03-30
Abstract: The measured values and data (features) of an object which is functioning with faults are evaluated using the method, so that the result is a series of causes (hypotheses), in descending order of probability. Two files are used for this purpose. A file 1 contains the set of permitted hypotheses, and, for each hypothesis, the set of features which are caused by this hypothesis and can be used to evaluate it. One file 2, which consists of a representative list of documented incidents, is used for statistical determination of the probability values which are required for the calculation. If the features (which may be uncertainly specified) of an object which is functioning with faults are known, a conditional probability of occurrence is calculated for each permitted hypothesis, using the so-called L-set. For the calculated hypothesis probabilities, an error calculation can also be carried out. The necessary calculation formulae and an associated flowchart are given.

Title: Method of combusting fuels as well as combustion installation
Inventor: MEIER HEINZ
IPC: F23K1/04
Filed: 1987-06-12
Abstract: In a combustion installation, the fuels are first comminuted and subsequently dried before they reach the combustion chamber. The drying heat is extracted from the combustion installation itself and the heat arising on the separation of moisture and fuels is supplied to the energy circuit of the combustion installation again, the combustion air being heated in a heat exchanger. A further energy recovery takes place by the dried comminuted fuels having a raised thermal value. The novel combustion installation thus makes possible for the first time the economical use of regenerable raw materials as moist fuels.
